Description

[Detailed description of the invention] [Industrial field of application] The present invention is a rapid transport system suitable for lifting and transporting granular materials such as sand, sieve residue, crushed stone, and sand to a high position in water treatment plants. This relates to an incline belt conveyor.

[Conventional technology]

BACKGROUND ART Conventionally, a chain conveyor with flights as shown in FIG. 5, which is an explanatory view of the main part, has been used to continuously lift and transport sediment generated in, for example, a water treatment plant. In the same figure, sprocket wheel 3
A chain 33 is endlessly rotatably wound between 1 and 32.
A plurality of flights 34 are attached at equal intervals to the trough 35, and are moved within the trough 35 to lift up and carry out the sediment. The chain conveyor with the above configuration has a cover 36
It has advantages such as being able to be sealed tightly, allowing water such as sand to be drained during lifting and transporting, and furthermore, by using a bucket type flight 34, it is possible to transport on a steep slope. However, it has drawbacks such as not being able to be conveyed vertically, having many worn parts, and having a large bending radius, making it difficult to shift from a horizontal state to an inclined state.

As a solution to the above drawbacks, there is a corrugated conveyor shown in FIG. 6, which is an explanatory view of the main part. In the figure, a driving pulley 41 and a driven pulley 42
A belt 43 is endlessly rotatably wound between the two, and is arranged in, for example, an S-shape via disc rollers 44 and 45. As shown in an enlarged perspective view of the main part in FIG. 7, the belt 43 is provided with corrugations 46 formed in a corrugated manner near both end edges and a transverse strut 47 perpendicular to the running direction of the belt 43. The corrugated conveyor having the above-mentioned structure has the advantage that it is possible to lift and unload in a vertical state, and also that it can prevent the conveyed objects from falling or being scattered during lifting and unloading.

[Problem that the invention attempts to solve]

However, in the corrugated conveyor having the above configuration, since it is necessary to fix the corrugations 46 of a special shape, the structure is not only complicated, but also the conveyed objects may adhere to the surface of the belt 43 or the corrugations 46 and peel off. The problem is that it is difficult. In addition, the shape of the belt 43 must be changed depending on the angle at which it is disposed, and there is also the problem that the deodorizing means becomes relatively large-scale when the conveyed material is sand or sieve residue. ing. Furthermore, since the disc rollers 44 and 45 shown in FIG. 6 are configured to press both ends of the belt 43 at the bent portion,
As shown in FIG. 7, the disk rollers 44, 4
There is also the problem that it is necessary to provide 5 pressing parts, which reduces the effective width of the belt 43 and reduces transport efficiency.

It is an object of the present invention to solve the problems existing in the above-mentioned prior art and to provide a belt conveyor for steep slopes having a large effective belt width and high conveying capacity.

[Means for solving problems]

In order to solve the above-mentioned problems of the prior art, in the present invention, a flat belt made of a flexible material wound endlessly between a driving pulley and a driven pulley is provided with an outer surface perpendicular to the running direction of the flat belt. A plurality of cross beams made of a rigid material are arranged so as to protrude from the outer surface of the flat belt, a lodging plate made of a flexible material is fixed to the cross beams, and a plurality of horizontal beams made of a rigid material are attached to both ends of the horizontal beam. A side cover is fixed thereto, and a guide roller is provided so as to be freely rollable, and the side cover shields both end edges of the flat belt, protrudes from the inner and outer surfaces of the flat belt, and overlaps and slides into contact with another adjacent side cover. They adopted a technical means to form it in this way.

[Effect]

With the above configuration, on the conveyance side, the horizontal rails and the falling plate provided so as to protrude from the outer surface of the flat belt prevent the conveyed object from falling on the flat belt in a steeply inclined state, and the horizontal rails at both ends The side cover provided on the belt allows the transported objects to be lifted and transported without being scattered outside the belt. Furthermore, since the crossbars made of a rigid material are provided at right angles to the running direction of the flat belt, it can be expected that the flat belt will run smoothly without deformation even at bends in the running path.

〔Example〕

FIG. 1 is an explanatory diagram of main parts showing an embodiment of the present invention. In the figure, 1 is a casing trough;
An input port 2 and a discharge port 3 are opened at an input place and a discharge place for sand etc., respectively, to form a substantially S-shape via a vertical transport section 1a. A driven pulley 4 is provided near the input port 2 and the discharge port 3 of the casing trough 1, respectively.
A drive pulley 5 is provided, and a flat belt 6 made of a flexible material is wound endlessly rotatably in the direction of the arrow. The driven pulley 4 is attached to, for example, a take-up device (not shown) and is movable in the horizontal direction, so as to apply a predetermined tension to the flat belt 6.

2 and 3 are a partially sectional side view and a plan view showing an enlarged configuration of the flat belt 6 in FIG. 1, respectively, and FIG. 4 is a sectional view taken along the line A--A in FIG. 2. In these figures, a plurality of horizontal rods 7 made of a rigid material are provided on the outer surface of the flat belt 6 at approximately equal intervals at right angles to the running direction of the flat belt 6. The crosspiece 7 is formed, for example, into a substantially U-shape from equilateral angle steel, and is fixed to the flat belt 6 via bolts, nuts, rivets (none of which are shown), or the like. Next, Yokogi 7
A side cover 8 made of a rigid material such as an iron plate is fixed to both ends of the plate, and a guide roller 9 is provided so as to be able to freely roll. Note that the side cover 8 is
For example, it is formed into a trapezoidal shape, and the side with the larger base size is disposed on the outer surface side of the flat belt 6. Further, the side cover 8 is configured so as to cover both end edges of the flat belt 6 even at the bent portion shown in FIG.
It is preferable that the side cover 8 is formed so as to overlap with another adjacent side cover 8 on either the inside or the outside, and that the side with the smaller base dimension also faces the inner surface side of the flat belt 6. Reference numeral 10 denotes a lodging plate, which is made of rubber or other flexible material and is fixed to the horizontal leg 7, and when a load of a predetermined value or more is applied to the free end,
It is formed so that it can be laid down in a direction opposite to the running direction of the flat belt 6 (counterclockwise in FIG. 2).

The operation of the above configuration will now be described. First, when an object to be conveyed, such as sediment, is inputted from the input port 2 shown in FIG. 1, the object is transferred onto the flat belt 6 and conveyed in the direction of the arrow. Next, when moving from the horizontal transport part to the vertical transport part shown by 1a, the guide roller 9 enters and moves into the guide 11 arranged facing the edge of the flat belt 6, and the flat belt 6 can smoothly transition from the horizontal direction to the vertical direction. Next, in the vertical conveyance section 1a, the outer surface side is closed by the casing trough 1, and the flat belt 6
Both end edges of are covered by side covers 8. Further, since the flat belt 6 is provided with a plurality of cross bars 7 and lodging plates 10 made of a rigid material at right angles to the running direction of the flat belt 6 as described above, the conveyed object is completely sealed. No inconveniences such as scattering or falling will occur. Note that at the bent portion of the flat belt 6, only the both end edges of the flat belt 6 are supported by the guides 11 and guide rollers 9, but a cross member 7 made of a rigid material is provided at right angles to the flat belt 6. Therefore, it is possible to prevent the inconvenience of the flat belt 6 curving in the width direction. Further, since the side covers 8 are provided on both ends of the flat belt 6 so as to overlap each other, the conveyed object does not fall to the both ends of the flat belt 6.

The conveyed object thus conveyed is discharged from the discharge port 3 by reversing the flat belt 6 at the drive pulley 5. Note that if a device such as a heater cleaner (not shown) is provided near the discharge port 3 and hits the flat belt 6 from the back side, the peeling action of the conveyed object can be increased. Note that the lodging plate 10 provided on the horizontal rail 7 maintains sufficient rigidity to support the weight of the conveyed object in the vertical conveyance section 1a, but is configured to collapse when a load exceeding a certain level is applied. This has the effect of preventing accidents such as jamming caused by, for example, a large object having an abnormally large external dimension entering the casing trough 1 among the objects to be transported.

In this example, an example was described in which sand and sieve residue from a water treatment plant were transported as objects to be transported, but other granular materials such as gravel, coal, ore, chips, grains, etc. Applicable. Furthermore, although a case has been described in which a part of the casing trough is upright, the effect is the same even if the casing trough has an inclined part, or if the casing trough has an L-shape other than an S-shape, an inverted L-shape, or another shape. Next, the material forming the crossbars provided on the flat belt may be made of materials other than steel, and can be appropriately selected in consideration of the properties of the conveyed object and other factors. It is not limited to only what is shown. Note that the materials constituting the flat belt and lodging plate can be made of other flexible materials such as rubber, and of course, composite materials with built-in canvas or other material as a core for reinforcement can also be used. It is possible. Furthermore, if the guide roller is provided with a groove so that it runs along the guide rail, it is effective to prevent meandering when the flat belt runs.

[Effect of idea]

Since the present invention has the configuration and operation described above, the following effects can be expected.

(1) By means of horizontal beams and lodging plates installed on the flat belt,
Since it has the effect of containing and holding the conveyed object, it is possible to lift and convey the object in a steeply inclined or vertical position and at a high height.

(2) Since side covers are provided at both ends of the crossbar to cover the edges of the flat belt to accommodate and hold the conveyed objects, there is no scattering or falling of the conveyed objects during conveyance. Not only does it eliminate the need for a cover or skirt on a regular conveyor,
Extremely high conveyance efficiency.

(3) Since the flat belt is provided with horizontal beams, the rigidity of the flat belt is high, and the conveyance route can be freely selected, and the effective width of the flat belt can be increased, making it possible to improve the rigidity of the flat belt. It operates extremely smoothly, and is compact and occupies a small area.
